Application filed February 19, 1920. Serial No. 359,957.

T all whom it may concern:

c it known that I, WILLIAM MCDONALD, of Twin Falls, in the county of Twin Falls and State of Idaho, have invented certain new and useful Improvements in Two-Way Mowers, of which th following is afull, clear, and exact description.

The present invention relates to an improved two way mower especially adapted to provide an implement by means of which the operator is enabled to mow across the field and return without the necessity of going around the field to cut a successive swath, and to this end the inven ion embodies the utilization of a pair of oppositely disposed cutter bars and operating mechanism, and means whereby the cutter bar which has been used to mow a swath in one direction, may be lifted to inoperative position in order that the other cutter bar ma be used for cutting the next swath. In this manner the two way mower is used to cut a swath with the left hand cutter bar in one direction, and after the machine is turned around or reversed, the left hand cutter bar is lifted to inoperative position and the right hand cutter bar is utilized to cut the return swath.

In the accompanying drawings I have illustrated one complete example of the embodiment of my invention, wherein the parts are combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention. Only the necessary devices are illustrated for the purpose of exemplifying the invention, and inany of the parts and mechanisms usually accompanying the standard form of mower and forming operative parts thereof, are omitted in the interest of clearness, and it will be understood that colorable changes and alterations may be made in the depicted structure, within the scope of my claims, without departing from the spirit of the invention.

Figure l is a plan view of a well known tyoe of mower having the devices of my in vention operativcly connected therewith.

F 2 is a front view in elevation of the implement according to my invention.

Fig. 3 is a detail view of the locking bolt.

In the preferred form of the invention as illustrated in the drawings I have utilized a well known form of machine or implement and converted it for use with my invention,

latter bracnets are carried it being understood that the invention may be applied to existing machines or manufactured and specially constructed in the factory as part of a new machine. In either event, the well known implement having the two traction wheels 1, 1, is employed, the wheels supporting the implement on the main frame 2, and the usual seat 3 is illustrated for the driver or operator. The draft tongue i may be used for the attachment or a single draft horse, or the implement may be of the two-horse type as desired, and equipped with a pair of oppositely disposed cutter bars 5 andG of well known type, that are permitted to float over the ground and supported at the front of the implement as by rollers and R in Fig. 2.

The cutter bars, at their inner ends, are provided with the usual pivoted or hinged that are sup- 10, and these at the lower ends of the complementary tubular casings 11 and 12, forming frame members in connection with the main frame, and inclosing the connecting mechanism or gearing, as for instance screw bars, for operating the cutter teeth of the two cutter bars.

-he pitmen 13 and 14, supported on the casings 11 and 12, are of the usual strong and light material, and are connected to their respective disks 15 and 16, on shafts within the casings 11 and 12, to receive power from the internal gears 17 and 18 of the traction wheels, and transmit it to the reciprocal teeth of the cutter bars in usual The cutter bars 5 and 6 may be lifted or swung upwardly on their respective hinges 7 and 8, to elevate them from operative po sition, and also for the purpose of avoiding irregularities, stones, rocks, &c., in the path of the cutter bars, and for accomplishing this purpose utilize a reversible lift bar 19, rasnioner at its outer end with a detachable hook 19 and adapted for connection with the end 20 of the cutter bar through the in strumentality of an eye bolt 21 fixed to the end bar 20. In Figs. 1 and 2 the hook 19 is shown attached to the eye bolt 21, but it will readily be apparent that the bar may be shifted to the left side of the implement to couple. with the eye bolt 21 when desired.

t its inner end, the lift bar is supported by a rotary or oscillatable disk 22, reversible on its shaft 23, when it is desired to swing the lift bar to the opposite side of the impleposition. In this manner, when the mower ment, and the shaft is supported in bearings reaches the end of a swath, the cutter bar 24 for this purpose, the bearings being atthat has been used, is lifted to inoperative tached at the upper si le of the draft tongue position as the implement is turned around, in front of the drivers seat. In the periphand the opposite cutter bar, 5, is used in cry of the disk are arranged diametrically cutting the return swath. disposed notches 25 and '26, and the disk The side of the field along which the also has attached thereto a lift lever 27 by initial out is made determines the use of the means of which the disk may be turned on selected cutter bar. Thus if the right hand its shaft to lift the cutter bar through the cutter bar is to be used for the initial cut, lift bar. the lift bar 19 is detached at 1921, and The disk may be held stationary, in adthe disk, bar, and lever are swung over to justed position, to lock the cutter bar and the opposite side of the implement in Fig. lift bar, by any suitable means, and as one 2, and the hook 19 coupled to the eyebolt exemplifying device for this purpose I have 21, the lever then lying normally in dotted shown a slide bolt 28, longitudinally dispositlon of Fig. 2. posed with relation to the tongue 4% and Having thus fully described my invention, adapted to co-act with one or the other of what I claim and desire to secure by Letters the notches 25, 26 of the disk, by sliding into Patent isand out of operative engagement with the 1.
